Objectives: The objective of this case report is to find a therapeutic effect of Gyeji-tang in panic disorder patients, based on Shanghanlun provision. Methods: At patient's first visit, we had conducted a medical interview in order to diagnose the physical and mental symptoms of the patient. A questionnaire called BAI had been also used to measure the degree of anxiety in panic disorder. After all the diagnoses had been done, the patient was allowed to take 120cc of Gyeji-tang, three times a day for 25 weeks. 25 weeks later, we conducted a second medical interview to compare with the initial treatment and to evaluate whether his physical and mental symptoms had been decreased or not. Likewise, the patient was asked to fill out the BAI questionnaire to measure the decline of anxiety degree. Results: Based on Shanghanlun provision, the patient with panic disorder due to overwork was diagnosed as Tai-yang-bing. Considering that the patient was having dyspnea, 15th provision of Gyeji-tang was selected and administered for 25 weeks. After 25 weeks, we could have observed that the main physical symptoms such as palpitation, dyspnea, stifling, headache, and fatigue were moderately improved. Moreover, the BAI score, which was evaluated to measaure the degree of anxiety, was also decreased from 49 points to the level of normal condition, 16 points. Conclusions: A 44 year old male patient who suffered from panic disorder due to overwork was allowed to take 15th provision Gyeji-tang for 25 weeks, based on Shanghanlun Provision. In results, the main physical symtpoms including dyspnea, palpitation, stifling, headache, and fatigue, and mental symptom such as extreme anxiety were all effectively improved.

Although double-stage hanger is used in many homes for its space utilization and ease of installation, it is inconvenient for users to take off clothes hung on the upper bar due to its high height. Therefore, this paper proposes a new type of double-stage hanger that allows users to easily hang or take out clothes hung on the upper bar while maintaining the function of the existing double-stage hanger. 4-bar link mechanism is applied so that the upper bar can come down to a convenient height with one operation. In addition, an appropriate link shape, length, and joint type are selected so that the height is adjusted three-dimensionally to prevent overlapping of clothes hanging on upper/lower bars. FEA analysis is performed to ensure that the presented hanger shape can support the load of clothes during height adjustment and the feasibility of the three-dimensional height adjustment hanger is verified through fabrication.

The influence of normal stress perpendicular to the potential shear plane was always neglected in existing researches, which may lead to a serious deviation of the shear strength of concrete members in practice designs and numerical analyses. In this study, a series of experimental studies are carried out in this paper, which serves to investigate the shear behavior of concrete under compression shear loading. Based on the test results, a three-phase shear failure model for cohesive elements are developed, which is able to take into consideration the influence of normal stress on the shear strength of concrete. To identify the accuracy and applicability of the proposed model, numerical models of a double-noted concrete plate are developed and compared with experimental results. Results show that the proposed constitutive model is able to take into consideration the influence of normal stress on the shear strength of concrete materials, and is effective and accurate for describing the complex fracture of concrete, especially the failure modes under compression shear loadings.

There is broad agreement that emissions from the shipping sector play a large role in the global climate change debate. In theory, there is broad consensus that the industry must take decisive action to reduce greenhouse gas emissions and do its part to combat global warming. The United States has made great strides in addressing emissions from ships, but it is the IMO that plays a key role in shaping global standards for the shipping industry. In the case of Korea, legislation on emissions issues has been prepared, but there are still problems with administrative power. IMO's high-level vision and change, as seen above, requires intensive efforts from industry representatives and requires intensive measures from the government responsible for implementation. It is necessary to consider regulations and the position of the shipping market. However, out of consideration and respect for the urgent reality of global climate change, ship owners, operators and holding companies will need to take voluntary steps to reduce GHG emissions instead of waiting for a new regulatory framework.

This paper analyzes Korean residential tenure choice for house which is the most important in Korean households' assets. Data used in the analysis is the data of Korean Labor and Income Panel Study for the period from 1998 to 2006 and with 2341 households. In this paper, a household chooses a housing tenure mode, either by renting or by owing house. We use a mixed-logit panel model as an estimation model to take into consideration household's heteroscedasticity of preference in tenure choice. It turns out that the heteroscedasticity is significant in households' tenure choice behavior, implying that Korean housing policy emphasizing supply side should consider the demand side.

The transformer inrush current can cause a voltage drop by source impedance. This current can impact sensitive loads by the voltage drop. Therefore, it is necessary to take measures to limit this inrush current. This study, described in this paper, analyzes the power quality affected by transformer inrush current using the X power system in Korea. The Electromagnetic Transients Program(EMTP) is used to analyze the transient phenomenon. We discuss a method to model the hysteresis curve of the transformer in EMTP. We carried out various simulations to analyze the power quality during transformer energization. The analysis results of voltage drop by the inrush current occurrence when certain requirements are met are presented.
